Just promoted a hearthling to a farmer and the symbol to place crops is still not highlighted so we can place. Or is this a new update and you need to do something first?
@Ayla did you have your game paused perhaps?
I can’t reproduce this. As @genboom says, once they finish the promotion animation the UI should refresh; if not, you can reopen the zones menu or refresh with F5. As far as I know, there’s no tutorial for farming so it shouldn’t be affected by it.
If you see it happening again, please upload a savefile so we can check it.
Edit: Yang confirmed they’ve seen this too sometimes.
FYI, @yshan is working on this bug in this morning’s stream. Will update this if she manages to resolve it. Has to do with client-server communication issues.
Update: Looks like Yang was able to resolve this on stream. I would expect this to be fixed in the next release.
